Kieffer's original description of Chironomus nudipes

Male.  Head, palps, scape and thorax reddish, antenna brown; mesonotum whitish yellow and lustrous, with three furruginous bands, of which the median is gradually becoming thinner into a line percurrent to the rear, the laterals foreshortened at the front; halteres white, legs yellow, the two or three last segments of tarsi becoming darker; anterior half of abdomen green, posterior half brown like the claspers.
Eyes separated by the distance of their own width. Segments 3-13 of the antennae a little transverse(?), 14th half as long again as the 12 previous segments together, plumes brown.
Wings hyaline, veins pale, radius equally distant from the point of the wing as the anterior branch, very near to the 2nd longitudinal; cubitus not extending beyond the costal, more distant from the point of the discoidal; crossvein oblique, situated above the bifurcation of the posticale.
Anterior metatarsus nearly double the tibia, which is a little shorter than the femur, 4th segment longer than the 3rd, more than twice as long as the 5th, the latter 8 times as long as wide(?); claws without long hairs, subglabrous.
Lamellae of the claspers with a prolongation to a point, terminal segment a little longer than the basal, slightly thinner at its rear, lobe extending notably to the middle of the terminal segment.
